type for transmission-shafts and the like, de-

signed with a view to presenting large rubbing-surfaces, to having none of the ordinary cross-pins, and to allowing easy and rapid dismembering and reassembling.

The description'is given hereinafter with reference to the annexed drawings, in which-.

Figure 1 is an external elevation of the arrangement assembled. Figs. 2 and 3 are two 'views which are longitudinal sections at right angles one to the other. tlOIl upon line 4 4 of Fig. 1.

Fig. 4 is a cross-sec- Figs. 5 and 6 are two longitudinal views at right angles, corresponding to Figs. 2 and 3, but showing the device in process of assembling. Fig. 7 represents in end view that one'of the forks in which are engaged the spherical junctioncaps. Figs. 8, 9, and 10 on the one hand, and 11, 12, and 13 on the other hand, represent separately the two spherical junction-caps. Figs. 14 and 15 represent a washer or kernel intended to be engaged between the branches of one of the forks.

This universal-joint devicecomprises two fork-shaped members A and B, attached to the two shaft portions a and b to be connected,

these two similar forks being placed in two planes at right angles one to the other. The prongs or arms of these forks are in the form of an arc of a circle. B are connected. together bymeans oftwo spherical caps C C and a kernel or washer D. The two parts G C are shown in detail in Figs. 8, 9, and 10 as regards one of them and in 11, 12, and 13 as regards the other. They have the shape of a spherical cap, along a great circle ofwhieh is cut a groove 0 of such size that these two parts 0 can be en gaged by these grooves upon the curved arms of one of the forks, in the drawingsthe fork A. The dimensions.of these caps C C are such that when they are thus engaged in These two forks A and faces corresponds to the thickness of the arms of the other fork B, so that the latter can be engaged in this space, being thus placed in a plane at right angles to the fork A. In the empty space existing between the arms of the fork B thus engaged between the flat faces of the two caps C is inserted a small washer or kernel D of corresponding shape. The whole is assembled by means of a bolt E engaged in a hole assing through the two caps C and the kerne D.

This universal joint device presents the advantage of being very strong, of havingno cross-pins, of presentin large rubbing-surfaces, and of being easi y and rapidly taken apart and replaced. It will be remarked that the security-bolt E has only to main- .tain the parts assembled, but undergoes practically no strain, and has'inno way the function of the ordinary cross-pin or an axle. The invention may of course be carried out with all modifications which are consistent with the general arrangement described.

Having thus described my invention, wh'aa I claim as such, and desire to secure by Letters Patent, is 1 1. A joint device of the Hooke or univers al type, formed of two forks with circular arms attached to the two shafts to be conthe fork A the clearance between theirflatnected, of two spherical caps provided along a great circle with a'groove by which they are engaged upon one of the forks and of a kernel inserted between the arms of the other fork engaged between the flat faces of the two'spherical' caps before mentioned, in combination with means to retain the parts in operative position. i

2. A universal joint comprising a forked member secured to the one shaft, a second forked member secured to the second shaft, said second fork being in a plane at right angles to that of the first, a washer arranged-between the forks of one forked member, a'cap arranged about each fork end of the other member, said caps bearing upon opposite faces of said washer, and means for maintaining the parts in position.-

3. A universal joint comprising a forked member, a second forked member whichis at right angles to the plane of the first, a washer located-between the forks of one ofthe said name to this specification in the presence of nii eriibersi a csgp arrgnged about elich fOlif) end 1 two subscribing witnesses. 0 i116 0t 1er orke member, sai caps earing upon opposite faces of said washer, and j EMILE LEON PROSBER 5 a security-bolt passing through said caps and I Witnesses:
